LeBron James may still be smarting from his Finals loss to the dominant Warriors, but it appears he found an effective outlet for his frustrations over the weekend—pelting dozens of ten-year-old kids with water balloons.

The water balloon fight was one of many activities that King James had planned for his son Bryce Maximus tenth birthday. The sports-themed party also included a painted field for activities and custom Niked uniforms for all party guests. The basketball legend shared highlights, along with some very kind words for his son, on his Instagram account.

James dominated the balloon fight then threw down on a lowered basketball hoop. The birthday boy’s cake came complete with his own logo, similar to the one his dad sports on his signature gear.

A few more days like this and the Cavs’ finals will be a distant memory.
